Hi Cowboy
1/8" blades can be tricky to keep running true,,,they get bigger as time goes on,,,, they can't take the full load of the spring the norm and if they sit for a long time with the load on them they will get bigger
You should always take the load off at the end of the day after you use them and they can't take the heat from cutting hardwood...if you look at the blade and you see that BLUE color in the blade other than the weld spot ,WELL...
It maybe time to replace the one you have with a new one, it may cut like a almost new one but if it goes off the line well it's not much good for what you want to use it for...
Springs are springs and it's hard to damage one with just a load on it now if they get hot well it maybe time to replace it also...they do make hvy.duty springs but they are for the bigger band saws and are made for resawing the norm..the welds on 1/8" blades like to snap if the load is to high..bearing work best for 1/8" band saws blades other than the rub/cool blocks, you can get kits for most of the band saws to put bearing in for the guide blocks...guide blocks do like to take the edge off the blade and will do it if hits it one time, it's gone in a heart beat...

I found the following chart: http://www.bandsawblade.com/chart.htm
It indicates that blade tension and tooth set (both mentioned in posts here) are two likely culprits two issues.
I'm glad that tightening the tension solved your problem
It hasn't helped me yet 
With the tension set until the spring is almost fully compressed (a no-no) I am still having the problem.
Given that this was a display model -- and had probably sat unused but under tension for MONTHS -- is it likely that the spring itself could stand replacing?
Or is the blade (1/8th") a more likely culprit? |
